340 build ideas

First things first. Sell the headers. Hooker 5204 minimum.
2.02 Valves.
10.0:1 -10.8:1 compression.
3.90 gears.
Holley Strip Dominator intake.
Custom cam from Racer Brown (first choice) Cam Motion (2nd choice) Jones cams (3rd choice) no off the shelf crap, especially with the stick.
McLeod Sof-Lok clutch (see threat in trans section on blown up parts).

That right there will easily put you in the low 12's all day long.


Well ignore ALL of my post. Forgot you have the early A body so the headers you have you prolly will have to use. Skip all of what I posted.
